Bowel components

Dublin Sisters Ceramic Red Colored Jewelry Apparently Illegal”:

2-4 letters of each component:

  • Duodenum
  • Sigmoid
  • Cecum
  • Rectum
  • Colon
  • Jejunum
  • Appendix

  • 3rd part: 4 inches
  • 4th part: 1 inch

Diaphragm apertures

3 holes, each with 3 things going through it”:

Aortic hiatus: aorta, thoracic duct, azygous vein.

Esophageal hiatus: esophagus, vagal trunks, left gastric vessels.

Caval foramen: inferior vena cava, right phrenic nerve, lymph nodes.

Diaphragm apertures: spinal levels

  • Aortic hiatus = 12 letters = T12
  • Oesophagus = 10 letters = T10

Liver inferior markings showing right/left lobe vs. vascular divisions

There’s a Hepatic “H” on inferior of liver. One vertical stick of the H is the dividing line for anatomical right/left lobe and the other vertical stick is the divider for vascular halves. Stick that divides the liver into vascular halves is the one with vena cava impression (since vena cava carries blood, it’s fortunate that it’s the divider for blood halves).

Liver: side with ligamentum venosum/ caudate lobe vs. side with quadrate lobe/ ligamentum teres

VC goes with VC“:

The Venosum and Caudate is on same side as Vena Cava [posterior]. Therefore, quadrate and teres must be on

anterior by default.

Meckel’s diverticulum details

  • 2 inches long.
  • 2 feet from end of ileum.
  • 2 times more common in men.
  • 2% occurrence in population.
  • 2 types of tissues may be present.

Note: “di-” means “two“, so diverticulum is the thing with all the twos.

Murphy’s point organ [for Irish]
